Method for detecting broken pin of drilling machine

Abstract

The invention discloses a method for detecting a broken pin of a drilling machine. The method comprises the steps of 1, designing the layout of inner holes of a plate to obtain the layout design drawing of the inner holes of the plate; 2, editing the layout design drawing of the inner holes of the plate by a script editor; adding a new hole at the side of the plate for the holes with the same type of aperture size on the original layout design drawing of the inner holes of the plate; enabling the drilling action of the new holes with different aperture sizes to be carried out after other holes with the corresponding aperture sizes are drilled, and taking the modified layout design drawing of the inner holes of the plate as a layout drawing provided with a broken pin detection module; 3, according to the layout drawing provided with the broken pin detection module, using the drilling machine to carry out the drilling work, obtaining a printed circuit board (PCB) subjected to the drilling work, and checking the new holes distributed at the side of the PCB to obtain the result of whether the broken pin exists in the drilling machine or not. The method is capable of reliably and efficiently detecting whether the broken pin exists in the drilling machine or not.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a method for detecting a broken needle of a drilling machine. Background technique [0002] For the drilling process of the PCB board, the traditional production method is to directly use the drill needle to drill the hole on the PCB board, but if the diameter of the drill needle is small (the diameter of the mechanical drill is between 0.15MM-6.5MM), the drilling It is easy to break the needle during the process, and because the aperture is too small, it is difficult to observe with the naked eye, even if the needle breaks, it is not easy to be found; the existing detection method is through manual detection, that is, it takes a lot of time to inspect each hole of the PCB board. Check to ensure that all the holes on the PCB board have been drilled through; but this method consumes a lot of manpower on the one hand, on the other hand, the detection effect is not ideal, and misse...

[0002] For the drilling process of the PCB board, the traditional production method is to directly use the drill needle to drill the hole on the PCB board, but if the diameter of the drill needle is small (the diameter of the mechanical drill is between 0.15MM-6.5MM), the drilling It is easy to break the needle during the process, and because the aperture is too small, it is difficult to observe with the naked eye, even if the needle breaks, it is not easy to be found; the existing detection method is through manual detection, that is, it takes a lot of time to inspect each hole of the PCB board. Check to ensure that all the holes on the PCB board have been drilled through; but this method consumes a lot of manpower on the one hand, on the other hand, the detection effect is not ideal, and missed inspections often occur, resulting in an increase in defective boards, which seriously restricts the long-term development of enterprises. develop
